    sferrin is referring to published, unclassified artwork at the time, not the real submissions.

    The MFI would have had excellent subsonic and supersonic manouverability, and an excellent supersonic cruise capability.

    Typhoon was valued about $50 million unit cost in 2002, but closer to $75 million for a complete package (e.g. Austria, 24 for $1.76 billion).

    Interesting site!

    This was used to test early configurations for the Mikoyan 1.42 in 1986-1992.
    The models had the modular design concept. The versions of aerodynamic layout permitting to realize controlled high-angle-of-attack flight under the full airflow breakaway were completed with these models. The problems of aerodynamic and gas-dynamic control methods combination, control system structure and laws were investigated during the flight tests at supercritical angles of attack, under the stall and spin conditions.

    The obtained research results allowed to receive a series of advanced aerodynamic layouts for high manoeuvering aircraft.

    These models were used in the Berkut program

    SLM-22

    The following research programs were performed with the model:

    Research of stability, controllability, stall, spin and methods of spin recovery for an aircraft with the forward-swept wing and different control laws also;

    Research of pressure distribution, air vortexes trajectories and airflow over the surfaces of plane units visualization;

    Research of air consumption through the engine gas flow duct effect to the stability and controllability characteristics.

    The model was created in period from 1988 to 1992 and tested till 1999.

    The model was the further development of SLM-22 model. It was equipped with turbojet engine.

    The following research programs were performed with the model:

    Research of stability, controllability, stall, spin and methods of spin recovery for an aircraft with the forward-swept wing and different control laws also;

    Research of effect of power plant operation mode to the streamlining, stability, controllability, stall and spin characteristics.

    Yes, thats based on a drawing I did which was loosely based on a TsAGI test model for a tailless delta design.

    The artist has added a side view.

    I’d be very surprised if it looked anything like the Mikoyan PAK-FA project. I imagine that was a twin engine (RD-33 derivatives) tailless delta looking like a scaled down/tidied up 1.42.

    PiBu: nice pic, do you know when it was taken?

    I presume you mean Kh-31, the anti-ship missile, not X-31 the vectored thrust test aircraft, in which case the answer is that the US Navy bought some (as “MA-31”) to use as target drones for shooting at with Aegis.

    I’m sorry Harry but that is irrelevant, its an IAPO Su-30MK brochure. Unless you believe Su-30MKI uses L-150 Pastel RWR, why should it have any bearing on the Su-30MKI’s OLS? India had the option, other potential MK users might have taken it up. Why on earth would India want a completely redundant laser designator in the IRST, which requires the host aircraft to dive on its target and is only compatible with missiles, not LGBs, when they are buying a modern pod like Litening which is much more useful?

    The IRST parts of the two are identical, and squarely based on the OLS-27K.

    Thanks Harry, I’ve got some confirmation of that.

    Note the Su-27 😉

    From paralay.narod.ru; some Berkut aerodynamic test models. Looks Soviet era…

    Trident: I’m gathering a little team and installing software, should be up soonish.

    Its from http://paralay.narod.ru, and its fake. I’d like to see the original though!

    AL-31F has a turbine entry temperature of 2500F.

    Presumably the internal ECM system would have a different designation?

    VEH 3020 is the Mirage 2000-5 Holographic wide angle HUD. VEH 3022 is the Rafale HUD. I can’t find VEH-3000 but presumably it would be very similar to these two models.

    GeorgeJ; if the VEH-3000 is anything like the Rafale’s VEH-3022 it probably wouldn’t fit inside the Su-30MKI’s cockpit 😉

    Seriously, the El-Op HUD is probably cheaper, and a better fit for retrofitting to MiG-29, MiG-27 etc. Makes sense to standardise on one type where possible, and the 967 series comes in several flavours for different machines.

    The earliest reports said “El-Op or Sextant Avionique VEH-3000 HUD”. In 2002 when the first MKIs were inducted, a Flight International report correctly mentioned an El-Op HUD but this seems to have largely been ignored.

    The “SU 967” seems to be a specific modification for India – it is for “MiG-29, MiG-27, Su-30” (http://www.elbitsystems.com/productsDetailsPage.asp?id=845)

    Also the MKI ECM system is designated EL/L-8222 not EL/M-8222 as widely stated and is carried in external pods, not internal. Given that the Su-27 family use external ECM, it seems unlikely that the Su-30MKI found room inside for an ECM suite.

    I can’t find any references as to which model Litening pod MKI will use. It appears that the Mirage 2000s might use Litening II but I can’t find any photographic evidence.
